How To Change the SQL Password Using RDO

MORE INFORMATION

Step-by-Step Example

1. In a new project add two CommandButton to the form.
2. Copy the code in step 4 into the Form's Declaration section.
3. Change the values for the password/username variables.
4. Change the connection properties to match your connection. Note that this example uses a DSN-less connection:

      Private Sub Form_Load()
        Command1.Caption = "User"
        Command2.Caption = "Admin"
      End Sub
   
      Private Sub Command1_Click()
      'This procedure is an example of allowing the users to change
      'their own password.
   
        On Error GoTo ErrorHandler
   
        Dim En As rdoEnvironment
        Dim Cn As rdoConnection
        Dim Ps As rdoPreparedStatement
        Dim strConnect As String
        Dim strSQL As String
        Dim strOldPassword As String
        Dim strNewPassword As String
   
        Command2.Enabled = False
   
        'Change the following to match your values
        strOldPassword = "OldPwd"
        strNewPassword = "NewPwd"
        Set En = rdoEnvironments(0)
        En.CursorDriver = rdUseOdbc
   
        strConnect = "Driver={SQL Server};Server=MyServer;" & _
           "Database=pubs;Uid=UserID;Pwd=" & Trim(strOldPassword)
   
        Set Cn = En.OpenConnection(dsName:="", Prompt:=rdDriverNoPrompt, _
        ReadOnly:=False, Connect:=strConnect)
       'Note that the above is a DSN-less connection
   
       'Note: If you don't specify master, you will get this following error:
       '"An invalid parameter was passed."
   
        strSQL = "{ ? = call master.dbo.sp_password(?,?) }"
        Set Ps = Cn.CreatePreparedStatement("", strSQL)
        Ps.rdoParameters(0).Direction = rdParamReturnValue
        Ps.rdoParameters(1) = strOldPassword
        Ps.rdoParameters(2) = strNewPassword
   
        Ps.Execute
        Debug.Print Ps.rdoParameters(0).Value
        If Ps.rdoParameters(0) <> 0 Then
         MsgBox "Could not change password"
        Else
         MsgBox "Password has been changed"
